You can get it from Espace Maison et Jardin at ShopRite in Trianon. It's called Dynaroot and it's a rooting hormone powder. It costs Rs53 and is much cheaper than what you will get at Mr Bricolage.
They also sell fertilizers and composting material along with seeds for flowers and vegetables. You can also get plants there but the prices are a bit steep. A coriander costs something like Rs45 while spring onion is Rs35. Might be better to grow it yourself.
